Earnings estimate revisions are the most powerful force impacting stock prices.

Stocks with rising earnings estimates, as a group, have materially outperformed the S&P 500 year-after-year. Similarly, stocks with falling earnings estimates have underperformed the S&P 500 year-after-year.

Zacks has made the process of identifying stocks with changing earnings estimates easy and very profitable. Since 1988, a portfolio constructed of Zacks #1 Rank stocks has generated an average annual return of 30%. Even during the 2000-2002 bear market, the strategy generated positive returns.

The Zacks Rank is a quantitative model that uses four factors related to earnings estimates to classify stocks into five groups, ranging from "Strong Buy" to "Strong Sell". We continually process reports issued by all the brokerage houses. At any given point in time, we are monitoring well over 200,000 earnings estimates and brokerage recommendation data points, looking for any change. Our ability to gather, analyze, and distribute information quickly makes Zacks' research among the most widely used on the web.

Zacks #1 Rank- A Strong Buy Recommendation
The Zacks Rank uses a five point scale for stock recommendations. A Zacks Rank of 1 has our "strong buy" rating- a virtual portfolio that has returned an annual average of 30%.

These are the stocks with upward revisions in earnings estimates, the most powerful indicator of potential price appreciation.

On the Zacks #1 page, you can view the current stocks with a Zacks Rank of 1, with quick links to quotes, industry outlook and in-depth company analysis. Narrow the list to particular sectors, or browse the whole list.

Zacks #5 Rank- Stocks You Should Sell Now
The Zacks Rank is proportionately applied to the entire universe of stocks with earnings estimates. So no matter how strong the economy is, only the very top 5% of stocks receive a Zacks #1 Rank. More importantly, approximately the same number of stocks are assigned a Zacks #5 Rank.

This equality between "Strong Buy" and "Strong Sell" recommendations makes the Zacks Rank a complete system to manage your portfolio. With daily access to the Zacks Rank, you'll see not only which stocks have a Strong Buy rating, but also which stocks you should sell right away. The #5 Ranking has been a good predictor of underperforming stocks. Since 1988, stocks ranked #5 have an average annual return of only 5.12%, less than half that of the S&P.
